Our study investigates the association between chronic periodontitis and plasma Hcy.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> This case\u2010control study involves 85 age\u2010 and sex\u2010matched subjects with chronic periodontitis and 91 healthy controls. Patients were grouped into moderate and severe periodontitis. Plaque index, calculus component of simplified oral hygiene index, and modified gingival index were recorded. Body mass index, fasting blood sugar, total cholesterol, triglycerides, high\u2010density lipoprotein, low\u2010density lipoprotein, very\u2010low\u2010density lipoprotein, and plasma Hcy were also assessed.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> Case and control groups had similar levels of fasting blood sugar, lipid profile, and body mass index. The mean plasma Hcy was found to be 19.22 \u00b1 8.27 and 10.27 \u00b1 2.50 \u03bcmol\/L for cases and controls, respectively. A significant elevation in plasma Hcy levels was observed in cases (<jats:italic>P<\/jats:italic> &lt;0.05).
